Methods: 1) Investigators will use FRAX®, cost-effectiveness and other key words to search Pubmed and international osteoporosis guidelines to better understand the clinical applications of FRAX® in other countries. Investigators will also search epidemiological data for osteoporosis, facture, quality of life and cost to establish domestic cost-effeteness, and translational approach FRAX® cut-points. 2) Three targeting populations from National Taiwan University Hospital (NTUH) are selected for prospective study (Group A: geriatric health exam clinics with American cut-points, group B: orthopedic clinics with translational approach cut-points and group C: endocrine clinics with cost-effectiveness cut-points,). A mobile device with app application coupled with the FRAX® tool is used by a trained research assistant during clinic waiting periods to screen and enroll high risk (75 from each clinic) adults with informed consents. Participants are referred to geriatric clinics for systemic osteoporosis diagnoses and managements. Percentage of participants that meet the current NHI medication reimbursement regulation and percentage of self-pay medications are calculated. Analysis is stratified by age and gender. 3) The impacts of 3 different cut-points on increment NHI reimbursement are estimated. An osteoporosis expert group meeting is to be held for FRAX® based osteoporosis medication reimbursement modifications to the NHI and the Department of Health.
